What happens if I forget the password?

The content is genuinely unrecoverable - that's what encryption means. Keep an unprotected copy somewhere safe, or store the password in a password manager.

How strong should the password be?

Length beats complexity: a four-word passphrase is both stronger and easier to share by phone than a short string of symbols.

Can recipients open it on their phone?

Yes - every standard PDF reader on every platform supports password-protected files. They'll simply be prompted for the password.

Is this the same as eSigning or certifying a document?

No - this controls who can read the file. Signatures are about who approved it. Different jobs, sometimes both needed.

Do you keep my password or file?

Neither. Files are deleted automatically after processing, and the password is used only to encrypt your file.

What you can do with PDF Password Protect

This tool encrypts your PDF with a password using the standard PDF security model. Anyone opening the file - in Adobe Reader, a browser, a phone - is asked for the password first. Without it, the content is unreadable.

When PDF Password Protect helps

Email attachments get forwarded, downloads folder pile up on shared computers, and cloud drives get synced to places you forgot about. A salary slip, medical report, or contract in plain PDF is readable by whoever encounters it. Encryption means an intercepted or misdirected file is just noise without the password.

How the PDF is handled

Upload the PDF, set a password, download the protected version. Send the password through a different channel than the file - if both travel in the same email, the lock is decorative. A text message or call for the password is the usual practice.
